How To Return To Stock Recovery

I unlocked the bootloader and installed TWRP on my Moto X Pure Edition XT-1575 with intentions of rooting it, but never did. I've recently been getting notifications to install an OTA update and can't do it with TWRP.
What's the easiest method to get my stock recovery back so I can install the update?

Do you have access to the factory images, if so you can flash recovery only and then take the OTA. Or you can just flash the image to your phone. Make sure to take out the -w for wipe and take out userdata.img So you can update without erasing data.
